The study found that the medication made marks on the DNA, with permanent consequences.

Ovaries exposed to paracetamol for one week had more than 40 per cent fewer egg-producing cells. After ibuprofen exposure, the number of cells was almost halved.
And testicular tissue exposed to painkillers in a culture dish had around a quarter fewer sperm-producing cells after exposure to paracetamol or ibuprofen.

Just reading it brings back the pain the Obamas must have felt but a must read.

"For eight years they watched you relentlessly demonize a black President; a man faithfully married for 26 years; a doting father and husband without a hint of moral scandal or the slightest whiff of infidelity.

They watched you deny his personal faith convictions, argue his birthplace, and assail his character—all without cause or evidence. They saw you brandish Scriptures to malign him and use the laziest of racial stereotypes in criticizing him.

The New York Police Department, with assistance from the Pentagon, is testing a scanning device that can remotely detect concealed firearms, Police Commissioner Ray Kelly said Tuesday.

The device measures natural radiation emitted by people and can detect when this flow of energy is impeded by an object, such as a gun.

"This technology has shown a great deal of promise as a way of detecting weapons without a physical search," Kelly said in a speech before a police group in Manhattan.

Known as terahertz imaging detection, the technology functions similarly to night-vision goggles, which detect infrared radiation. But unlike much infrared radiation, the terahertz wavelength is not blocked by clothing.

"With terahertz, you will be able to identify a gun as a gun," said John Federici, a physics professor at the New Jersey Institute of Technology.

What about one of these Long Distance Gun detectors set up at the only One Way entrance of schools?
Maybe? they could build Pre-Entry hallways that self lock if guns/weapons are detected - trapping the offender inside of it
until someone could come and check it out. All other entrances would be self locking and function as exits only.
